Forum Post: Inventory Stock Item

I am creating an invoice using stock inventory items... Lets say my invoice total is 1.00 for a flower. When I look at the GL it showes my job profit has a credit of 1.00, my inventory materials has a credit for 1.00, Accounts payable has a debit of 1.00 and Labor Cost has a debit of 1.00.  My question concern is that flower has a cost of 1.00 and i am not sure if i should or should not have a labor cost of 1.00 in cost of goods sold for a stock item.
